Abstract: Abstract A process for the recovery of nickel, cobalt or man-ganese from their oxides or silicates wherein such process, which requires the application of heat, is improved by utilizing microwave energy as the source of heat.  The microwave energy may be utilized to cause the reduction of these values enabling such reduced values to then be re-covered by conventional leaching processes.  The microwave energy may also be used in conjunction with the chlorination of such values to produce their chlorides which are sub-sequently separated from the gangue and then processed by conventional means to obtain the metal values.

Abstract: ABSTRACT OF THE DISCLOSURE      Increase or decrease in a quantity of alumina present in a bath or a metal in an aluminum electro-lytic cell is detected and a quantity of electric power supplied to the cell is increased or decreased in accordance with the result of detection.  The detec-tion is made by calculating a difference between a quan-tity of alumina supplied to the cell during an interval between an instant at which a previous anode effect has occurred or was anticipated to occur and an instant at which a present anode effect occurs or is anticipated to occur, and the quantity of alumina consumed during the interval.  According to this invention it is possible to stably operate the cell while maintaining the cell temperature at a constant value.

Abstract: ABSTRACT     A belt and pulley system for the transmission of power from the crankshaft of an internal combustion engine to a plurality of power consuming devices, such as a generator/alternator, a power steering pump, a power brake pump, etc.  The system employs a fluid shear pulley coupled to the engine crankshaft.  The pulley employs the principle of fluid shear transmission of torque for the purpose of isolating torsional vib-rations in the hub of the pulley from the outermost, belt-driving portion of the pulley.  By virtue of this system, torsional vibrations in the crankshaft are effectively isolated from the driving belt.  This isolation of vibrations precludes attainment of resonant modes of vibration in the driving belt, thereby extending the life of the driving belt and also making possible the use of lighter and smaller driving belt.

Abstract: ABSTRACT           A multi-stage turbine has an inflow disc pack that directs motivating fluid to an outflow disc pack on the same shaft.  The packs are fitted to rotate between plates that web a turbine casing interior and fluid entry into the casing to the inflow pack is via nozzles in a ring assembly fixed to the casing.  Each disc pack is made up by spaced apart discs with fences that guide the motivating fluid first through the inflow pack and then the outflow pack.  A central passageway in the packs and adjacent the shaft communicates fluid from inflow to outflow.  Fluid exhaust is through exits at the casing bottom.  In one version, the disc packs are conical and when seen from the side, the packs with webbed plates are X configured in section.  In another version, the inflow pack is flat, the outflow pack conical and the casing of both versions are configured to provide low losses and maximum strength.  The nozzles can be convergent-divergent in a plenum located adjacent the inflow pack circumference.

Abstract: ABSTRACT OF THE DISCLOSURE      TWO-LEVEL THRESHOLD CIRCUITRY FOR LARGE SCALE INTEGRATED CIRCUIT MEMORIES           This disclosure relates to circuitry which includes a low threshold detector and a high threshold detector in the form of inverters the respective output signals of which are combined in such a manner that the output signal of the circuitry is a function of the input signal rising above a low threshold and remaining in an on condition until the input signal has risen above a high threshold and then declined below it. In addition, the circuitry includes a circuit memory element in which is stored the last stable state of the circuitry so that if noise or transients should occur on the input line, the circuitry can return to that stable state.   This circuit enables the rapid detection of a memory readout even though the signals on the memory sense lines have relatively slow rise and fall times due to the capacitances on those lines which in turn are due to the large number of memory cells involved.  Furthermore, the disclosed invention can be employed in any system in which switching speed is of importance.
